I've been following this

by this file:

My problem is that in the created file, I have backtick r backtick n instead of linebreaks. Is it normal? Am I missing something?

I also tried using \r\n instead of backticks r backticks n and the same happens (it's recognised but in the output file there is \r\n and not an actual linebreak (I'm on Windows 11).

You need to use double-quotes for escape sequences, see about_Special_Characters.

An example for you to test:

$text = @'
test = 'lol'
lol = 'test'
'@

$text -replace "test = 'lol'\r?\nlol = 'test'", "test1 = 'lol1'`r`nlol2 = 'test2'"

As for your call to powershell.exe from the batch file, I believe this could work (you can use "^"" for escaping):

powershell -Command "(gc -Raw test.py) -replace "^""test = 'lol'\r?\nlol = 'test'""", """test1 = 'lol1'`r`nlol2 = 'test2'"^"" | Out-File test2.py"

All credits on the call to cmd and the required escaping goes to this answer.
